Preparation

Step 1
Preheat oven to 425 degrees. Toss the potatoes with the oil and 1 teaspoon of salt and transfer them to a greased baking sheet large enough to hold them in a single layer. Bake, turning the potatoes once, until lightly browned, 20 to 25 minutes. Set aside.
Step 2
Lower temperature to 400 degrees. Whisk together the eggs, ⅓ cup sour cream, thyme, ¾ teaspoon salt and a few grinds of pepper. Stir in the portobello caviar. Brush the mushroom caps with olive oil, season them on both sides with salt and place them gill-side up on a greased baking sheet. Lay the potato slices over the mushrooms, letting some hang over the edges of the mushrooms like petals of a flower. Divide the caviar mixture evenly into 4 parts, mounding 1 part in the middle of each mushroom cap. Bake until the filling is set and the mushroom caps are very tender, about 30 minutes. Garnish each mushroom with a dollop of sour cream and parsley and serve.
